Frequently Asked Questions (FAQs)
1. Can you buy new filters for air conditioners?
Regular air conditioner filter replacement is vital to maintaining the efficiency of your cooling system. As stated by the Environmental Protection Agency (EPA), the indoor air is 70% more polluted than outdoor air. Regular AC filter replacement can enormously improve the indoor air quality.
2. How often should air conditioner filters be changed?
Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
3. How do I know what filter to get for my AC?
The air filter is typically near the thermostat in your home in a return duct. Or, it's most likely right next to your AC system's air handler.
4. Are AC filters universal?
No filter is universal, so it's important to make sure the filter you purchase is the correct size to fit in your HVAC system.
